[libvirt] [PATCH v3 00/36] network: refactor to decouple virt drivers from network driver
by Daniel P. Berrangé
An update to
v1: https://www.redhat.com/archives/libvir-list/2018-December/msg00681.html
v2: https://www.redhat.com/archives/libvir-list/2019-February/msg01581.html
Currently the network driver registers a set of callbacks with the virt
driver in order to handle allocating/releasing network ports associated
with guest NICs.
This series introduces a virNetworkPortPtr object and associated XML
that describes a network port. The virt drivers now call public APIs
associated with this new object to create/delete ports for guest NICs.
Changed in v3:
- Remove unused API symbol
- Fix dist of test data files
Changed in v2:
- Fix many bugs related to upgrades with running VMs
- Convert over bandwidth controls to the new APIs
- Handle reconnecting VIFs to bridges during startup
- Much much more that I can't remember
Daniel P. Berrangé (36):
network: restrict usage of port management APIs
network: pass a virNetworkPtr to port management APIs
conf: simplify link from hostdev back to network device
network: add missing bandwidth limits for bridge forward type
network: use 'bridge' as actual type instead of 'network'
util: add helper method for re-attaching a tap device to a bridge
network: use virNetDevTapReattachBridge API
virt drivers: don't handle type=network after resolving actual network
type
network: move re-attach of bridge device out of network driver
network: move fixup for domain actual net def out of network driver
network: unconditionally merge port profiles
conf: don't pass interface type into virNetDevBandwidthParse
conf: introduce virNetworkPortDefPtr struct and XML support
network: stop passing virDomainNetDefPtr into bandwidth functions
network: make networkLogAllocation independent of domain conf
util: add API for copying virtual port profile data
conf: add APIs to convert virDomainNetDef to virNetworkPortDef
network: convert networkAllocateActualDevice to virNetworkPortDef
network: convert networkNotifyActualDevice to virNetworkPortDef
network: convert networkReleaseActualDevice to virNetworkPortDef
network: convert hook script to take a network port XML
network: remove the virDomainNetBandwidthChangeAllowed callback
network: introduce networkAllocatePort
network: introduce networkNotifyPort
network: introduce networkReleasePort
network: introduce networkUpdatePortBandwidth
network: add public APIs for network port object
access: add permissions for network port objects
remote: add support for new network port APIs
virsh: add support for network port APIs
conf: support recording ports against virNetworkObjPtr
network: add implementation of network port APIs
lxc, libxl: notify network driver of NICs during reconnect
lxc, libxl: save domain status after reconnect
conf: record a portid against the domain conf
conf: switch over to use network port APIs for virt drivers

[libvirt] [PATCH] qemu_hotplug: Remove virQEMUDriverPtr arguments
by Suyang Chen
Since commit 2e6ecba1bcac, the pointer to the qemu driver is saved in
domain object's private data and hence does not have to be passed as
yet another parameter if domain object is already one of them.
This just changed qemuDomainChangeDiskLive and
qemuDomainChangeEjectableMedia functions

[libvirt] [PATCH v3 0/6] Facilitate running libvirt builds via docker containers
by Daniel P. Berrangé
For a while QEMU has provided simple make rules for building QEMU inside
standard docker container environments. This provides an equivalent
mechanism for libvirt inspired by QEMU's.
QEMU actually builds the container images on developer's machines
locally. Libvirt already hosts pre-built images on quay.io, so that is
used directly as it is quicker to download them than to build them
locally. This also ensures the container contents match what the live
CI system is using, as opposed to building an image with newer packages.
NB, there is a currently a test failure with this change to travis
that we don't currently see. Current travis runs a privileged
docker container, but with this change we now run unprivileged
containers. This shows that the "virsh-snapshot" test is trying
to create a file under $HOME, and docker blocks this. Obviously
needs fixing before pushing.
Changed in v3:
- Lots of new variables & variable renames
- Rename to top level Makefile.ci
- Rename make targets to have @ separator for the image
- Refactor macOS travis config
Changed in v2:
- Drop cross-compilation patches temporarily. The cross-compiler
images are not yet built on quay.io and rather than creating and
bulding many more images manually, I'm working on script to
automate setup of quay.io images
- Many changes to the make rules to make it possible to use them
from Travis CI to match its currently testing setup
- Modify Travis CI config to use the new make rules for consistency
Daniel P. Berrangé (6):
tests: don't abort in fopen(/proc/mounts)
tests: add targets for building libvirt inside docker containers
travis: convert ubuntu, centos & mingw builds to use new make rules
travis: use declarative syntax for homebrew packages
travis: remove display of test-suite.log from macOS
travis: put macOS script inline in the macOS matrix entry

[libvirt] [PATCH v6 00/33] BaselineHypervisorCPU using QEMU QMP exchanges
by Chris Venteicher
Some architectures (S390) depend on QEMU to compute baseline CPU model and
expand a models feature set.
Interacting with QEMU requires starting the QEMU process and completing one or
more query-cpu-model-baseline QMP exchanges with QEMU in addition to a
query-cpu-model-expansion QMP exchange to expand all features in the model.
See "s390x CPU models: exposing features" patch set on Qemu-devel for discussion
of QEMU aspects.
This is part of resolution of: https://bugzilla.redhat.com/show_bug.cgi?id=1511999

Reviewed in v5 but no changes required:
qemu_process: Limit qemuProcessQmpNew to const input strings
qemu_process: Use consistent name for stop process function
qemu_process: Persist stderr in qemuProcessQmp struct
qemu_process: Store libDir in qemuProcessQmp struct
qemu_process: Setup paths within qemuProcessQmpInit
qemu_process: Stop retaining Monitor config in qemuProcessQmp
Not reviewed in v5:
qemu_monitor: Support query-cpu-model-baseline QMP command
qemu_driver: Consolidate code to baseline using libvirt
qemu_driver: Decouple code for baseline using libvirt
qemu_driver: Identify using libvirt as a distinct way to compute baseline
qemu_driver: Support baseline calculation using QEMU
qemu_driver: Support feature expansion via QEMU when baselining cpu
qemu_driver: Remove unsupported props in expanded hypervisor baseline output
qemu_monitor: Default props to migratable when expanding cpu model
-----
v5:
Fixes all process issues identified here:
https://www.redhat.com/archives/libvir-list/2018-November/msg00349.html
- Make the process code generic (not capabilities specific) for use by
BaselineHypervisorCPU
- Many of the process patches are simple code moves with implementation
changes in other distinct patches
- A thread safe library function creates a unique directory under libDir for each QEMU
process (for QMP messaging) to decouple processes in terms of sockets and
file system footprint.
The remaining (non-process) patches in v4 address all issues in v1-v4 of
'BaselineHypervisorCPU using QEMU QMP exchanges'
Thanks,
Chris
